Z is the 26th and final letter in the Alphablock gang.
Z is an elder-like Alphablock who can sleep almost anywhere.
Z is green with silvery-white eyebrows and beard and wears a badge on the right side of his chest. Sometimes he sports a walking stick.
Since Alphablocks aired in the UK, Z's name is pronounced "zed". But if America would air the show, then Z's name would be pronounced "zee".
Z is the only male green Alphablock.
The game version of Hat is the only episode where Z is moveable.
The only nonsense Z appears in are QWJZ and WQZJ.
